Tonight will bring blue moon event for you. Friday night's moon is the blue moon because it would be the second full moon in July. Lunar cycle is of 28 days and as the first full moon took place on July 2, the second was set for July 31.

It's once in 30 months when two full moons occur in one month. An extra moon is all once can take as a modern definition of a blue moon.

Barentine, a manager with the International Dark-Sky Assn, says the middle of the Sahara in Africa is the best place to go for the viewing of the blue moon as it is one of the darkest places in the world. People in LA should go out of the city if they really want to capture the view of the blue moon on Friday night.

It's very important to not have obstruction from city lights while you make an attempt to gaze at the sky and see the blue moon.

He suggested Southern Californian people to go to Death Valley National Park, Joshua Tree National Park and Anza-Borrego Desert State Park for the viewing of the blue moon tonight. Tonight's moon will be similar to other full moons; it's just the second full moon in the same month. The moon can appear a little bluish tonight because of the rare occurrences, such as during a forest fire.

Barentine's organization supports the creation and protection of natural spaces that are free of artificial light.
